The caution tape on the John Hancock Charter School playground in Pleasant Grove is to keep students away from collapsing swing sets.

Board members for the school said on Thursday they will alert parents this week that two students narrowly -- miraculously, officials said -- avoided being hit by metal piping when an 8-foot swing set on school grounds gave way.

Wendy Morgan, vice-president of the school's board, happened to witness the accident. She told board members that the set literally collapsed, with jagged metal in the air, to the point where she was afraid "there was going to be a liver somewhere" from an eviscerated child.

The welds on the top bar of the swing set broke, causing the collapse, said Julie Adamic, school director.

"When the bar fell, there were two students directly underneath it and it completely missed them," Adamic told the board.

Board members and parents at the meeting attributed the happy outcome to God, angels and a miracle, saying the school is relieved that no one was injured, or worse.

The accident, which happened just days ago, turned out to be a double blessing because when school officials called those who installed the swing set, they learned the welds on a second swing set on the playground were going to fail imminently, again because of faulty welds.

A section of the playground has been shut down, surrounded by yellow caution tape, and this has started some community members wondering if something terrible happened on the playground. Because of this concern, the school will alert parents about what happened in this week's newsletter, and tell parents what the school is doing about it.

The school initially asked that the sets be repaired, but has now decided to replace them entirely, Adamic said.

So how do you keep 180 K-8 children off broken swing sets?

"The students have been threatened with their lives -- even worse, with think-time," Adamic said. On Thursday, all that remained of the sets was support poles sticking out of the ground. Swings, and the collapsed bar, had been removed.

Also during Thursday evening's board meeting, the school took on bullies, per a new state requirement.

"We are now required to have an anti-bullying and anti-hazing policy, and we need to provide training," Adamic told board members.

And if you happen to think school surely hasn't changed all that much since you were a student, consider this: As part of the effort, the school is working on a cyber-bullying presentation that will teach children how to avoid becoming Internet bullies, and how to avoid being their victims.
